Just a friendly note of warning to all of the NVIDIA users out there
who have upgraded to use version 8174 of the NVIDIA driver that you could
be using a lot more CPU than with earlier driver versions.
It has been reported by a few people (myself included) that
using OpenGL Vsync with 8174 uses a lot more CPU than previous. Disabling
OGL Vsync or reverting to a previous driver lowers the usage back to
normal.
So if you are suddenly seeing some skipping video or other
cpu issues and you recently updated your video driver you might want to check
it out.
With 7676 my cpu usage was(on an XP2500+) :
With OGLVS
Playback : 12%
Paused : 0%
Without OGLVS
Playback : 13%
Paused : 0%
But with 8174 I had:
With OGLVS
Playback : 80%
Paused : 30% (That's right, 30% when paused)
Without OGLVS
Playback : 13%
Paused : 0%
